Abstract<br />

The purpose of this research was to study the determination of some slaughtering and carcass<br />

characteristics that ducks grown in free range and closed system and it sustained for 14 weeks.<br />

The study started with 240 daily ducks and all environmental requirements of them are provided<br />

until slaughtering. Prior to slaughtering, body weight of ducks were determined with 0.1<br />

accuracy scale. A total of 32 ducks were slaughtered by randomly choosing 1 female and 1 male<br />

close to average at each 1<strong>4th</strong> week. After slaughtering, hot carcass, edible internal organs (heart,<br />

liver, gizzard) and abdominal fat weights and ratios were determined. As a result, the breeding<br />
